sparc64: Handle hugepage TSB being NULL. Accomodate the possibility that the TSB might be NULL at the point that update_mmu_cache() is invoked. This is necessary because we will sometimes need to defer the TSB allocation to the first fault that happens in the 'mm'. Seperate out the hugepage PTE test into a seperate function so that the logic is clearer. Signed-off-by: David S. Miller <davem@davemloft.net>
